Step 4: Treatment
Targeted actives — serums, ampoules, and treatments for specific concerns.
Ada Tina's C 20 Serum is the Italian-Brazilian vitamin C treatment specifically formulated for melasma — the pigmentation condition that affects roughly 30% of Brazilian women and is notoriously difficult to treat in high-UV equatorial climates. Sodium ascorbyl phosphate (SAP) at 20% provides potent brightening and melanin inhibition without the instability of L-ascorbic acid — critical in a country where bathroom temperatures regularly exceed 30°C. Carnosine, an amino acid dipeptide, provides additional anti-glycation and antioxidant support. Dual hyaluronic acid (regular + sodium hyaluronate) provides hydration at two molecular weights. Olive leaf extract adds polyphenol antioxidant defence. The 10-ingredient formula is remarkably clean — no fragrance, no colourants, no unnecessary additions. Ada Tina was founded by an Italian dermatologist in São Paulo, and the formulation philosophy is distinctly Italian-clinical: maximum active concentration, minimum filler.

Microneedling's gentler, no-downtime sister — a silicone-tip cartridge oscillating at ~150,000 vibrations/min that pushes serums into the epidermis without piercing the skin.

A cocktail of vitamins, amino acids, and hyaluronic acid injected into the superficial dermis — French-born, globally adopted, endlessly remixed.
